Question

I have an Application with two Tabs in WPF. One is Used to add a customer to the Database. The Other tab displays the list of customers in a datagrid. My Problem is that when one adds a customer to the database, the new entry is not added into the Datagrid.In order for the customer to appear I have to close the application and rerun it. How can I ensure that when I add the customer it automatically appears in the list of customers in the datagrid? I am using Entity Framework..

Answer 1

Entity Framework does not know about your tabs and grids, it dont know about WPF at all.

But you can:

1. Update grid manualy
2. Use ObservableCollection’s.
3. Use http://waf.codeplex.com/
